Abstract

The invention provides an audio signal output method and device, a terminal, and a system. The method comprises the steps: enabling a first audio signal of a background music signal to be transmitted to a DSP (digital signal processor); receiving a third audio signal formed by the mixing of the first audio signal, returned by the DSP, with a second audio signal, wherein the second audio signal is an audio signal received from a microphone; and outputting the third audio signal. According to the invention, the method solves problems in related technologies that the audio output is large in time delay and the user experience is poor, thereby reducing the time delay of audio output, and improving the user experience.

Description

technical field [0001] The present invention relates to the communication field, in particular to an audio signal output method, device, terminal and system. Background technique [0002] High Definition Multimedia Interface (HDMI for short) is a digital video / audio interface technology and a dedicated digital interface suitable for image transmission. It can transmit audio and video signals at the same time, and the maximum data transmission speed is 18Gbps. At the same time, there is no need for digital / analog or analog / digital conversion before signal transmission. [0003] Karaoke is an accompaniment system. Singers can participate in singing with pre-recorded music accompaniment. Karaoke can beautify the singer's voice through sound processing. When combined with music accompaniment, it becomes a natural An integrated stereo song, this entertainment method, can bring extremely pleasant feelings to the public. The karaoke function has high requirements for real-time au...
